AIKhalili , MSc,PhDD. AIKhalili,MSc,PhD,MScABSTRACT: The basic function of the electric power system is to transport the electric power towards customers. The l0kV electric distribution net is a key point that connects the power supply with the electricity using on the industry, business and dailylife. For the electric power, all costumers expect to pay the lowest price for the highest reliability, but don39。t consider that it39。s selfcontradictory in the coexistence of economy and improve the reliability of the power supply network, we must increase the investment cost of the network construction But, if the cost that improve the reliability of the network construction, but the investment on this kind of construction would be worthless if the reducing loss is on the poweroff is less than the increasing investment on improving the reliability .Thus we find out a balance point to make the most economic,between the investment and the loss by calculating the investment on power net and the loss brought from poweroff.KEYWORDS: power supply and distribution, power distribution reliability，reactive pensation, load distributionThe revolution of electric power system has brought a new big round construction,which is pushing the greater revolution of electric power technique along with the application of new technique and advanced equipment. Especially, the bination of the information technique and electric power technique, to great ex tent, has improved reliability on electric quality and electric supply. The technical development decreases the cost on electric construction and drives innovation of electric network. On the basis of national and international advanced electric knowledge, the dissertation introduces the research hot spot for present electric power system as following.Firstly, This dissertation introduces the building condition of distribution automation(DA), and brings forward two typical construction modes on DA construction, integrative mode and fission mode .It emphasize the DA structure under the condition of the fission mode and presents the system configuration, the main station scheme, the feeder scheme, the optimized munication scheme etc., which is for DA research reference.外文翻譯Secondly, as for the (DA) trouble measurement, position, isolation and resume, This dissertation analyzes the changes of pressure and current for line problem, gets math equation by educing phase short circuit and problem position under the condition of singlephase and works out equation and several parameter s Uamp。 , s Iamp。 and e Iamp。 table on problem . It brings out optimized isolation and resume plan, realizes auto isolation and network reconstruction, reduces the power off range and time and improves the reliability of electric power supply through problem self diagnoses and selfanalysis. It also introduces software flow and use for problem judgment and sets a model on network reconstruction and puter flow.Thirdly, electricity system state is estimated to be one of the key techniques in DA realization. The dissertation remends the solution of bad measurement data and structure mistake on the ground of describing state estimate way. It also advances a practical test and judging way on topology mistake in state estimate about bad data test and abnormity in state estimate as well as the problem and effect on bad data from state measure to state estimate .As for real time monitor and control problem, the dissertation introduces a new way to solve them by electricity break and exceptional analysis, and the way has been tested in Weifang DA.Fourthly, about the difficulty for building the model of load forecasting, big parameter scatter limit and something concerned, the dissertation introduces some parameters, for example, weather factor, date type and social environment effect based on analysis of routine load forecasting and means. It presents the way for electricity load forecasting founded on neural network(ANN),which has been tested it’s validity by example and made to be good practical effect.Fifthly, concerning the lack of concordant wave on preventing concordant wave and nonpower pensation and noncontinuity on pensation, there is a topology structure of PWM main circuit and none power theory on active filter the waves technique and builds flat proof on the ground of Saber Designer and proves to be practical. Meanwhile, it analyzes and designs the way of nonpower need of electric network trends and decreasing line loss bined with DA, which have been tested its objective economic benefit through counting example.Sixthly, not only do the dissertation design a way founded on the marginal electric price fitted to our present national electric power market with regards to future trends of electric power market in China and fair trade under the government surveillance, that is group petition in shortterm trade under the way of grouped price and quantity harmony, but also puts forward bination arithmetic, math model of trading plan and safety economical restriction. It can solve the original contradiction between medium and long term contract price and short term petitive price with improvement on petitive p
